[0024] Each of the four side walls of the tank body 1 is provided with a heating chamber 13, to which a pump body 11 is fixedly connected. The input end of the pump body 11 is fixedly connected to a water inlet pipe 12, and the output end of the pump body 11 is fixedly connected to a water outlet pipe 14. When the pump body 11 is started, hot oil at high temperature in the external hot oil tank is drawn in through the water inlet pipe 12 and delivered to the water outlet pipe 14.
